IMB-NBC Benchmarks#
Intel(R) MPI Benchmarks provides two types of benchmarks for nonblocking collective (NBC) routines that conform to the MPI-3 standard:
Benchmarks for measuring the overlap of communication and computation
Benchmarks for measuring pure communication time
Tip
When you run the IMB-NBC
component, only the overlap benchmarks
are enabled by default. To measure pure communication time, specify
the particular benchmark name or use the –include
command-line
parameter to run the _pure
flavor of the benchmarks.
The following table lists all IMB-NBC
benchmarks:
Benchmarks Measuring Communication and Computation Overlap (Enabled by Default) |
Benchmarks Measuring Pure Communication Time (Disabled by Default) |
